It is the CPAP battery you can find on the market, more compact, lighter, and easy to carry along with.
Here is some testing data below.
Capacity test
The Easylonger EL240 has a capacity of 3.7V / 24000mAh / 88.8Wh.
Here is our reliable tester converted the information in theory.
5V: (88.8Wh / 5V) * 1000 = 17760mAh
9V: (88.8Wh / 9V) * 1000 = 9866mAh
12V: (88.8Wh / 12V) * 1000 = 7400mAh
16.5V: (88.8Wh / 16.5V) * 1000 = 5381mAh
20V: (88.8Wh / 20V) * 1000 = 4440mAh
24V: (88.8Wh / 24V) * 1000 = 3700mAh
The practical discharge test with 5V / 1A resulted in approx. 13,000mAh. The theoretical value should be 17760mAh. This is a deviation of 27%.
Measurements
Test 1: 12734mAh
Test 2: 13097mAh
Charge laptop
I charged a Lenovo laptop with 20V and an integrated 3900mAh battery. Then the rest of the power bank was discharged with 5V / 1A. The residual discharge with 5V / 1A was 9289mAh. So I could charge the laptop 3 times with the power bank and then there would still be some remaining capacity.
A total of 16 adapters are included so that you can charge various devices.
(7.4 / 5.0mm): DELL and HP
(5.5 / 2.5mm): DELL and HP with TOSHIBA and FUJUTSU and ASUS
(6.0 / 4.4mm): SONY FUJUTSU
(5.5 / 1.7mm): Acer
(4.8 / 1.7mm): HP and LG
(5.5 / 3.0mm): SAMSUNG
(7.9 / 5.4mm): LENOVO
Data and voltage values
The weight is 511 grams. If we press the button, the LED ring lights up. It shows the battery level. Each quadrant represents 25% capacity. Wireless charging with Qi-Charging compatible models is possible, maximum 10W. Press the button and hang up the cell phone. But unfortunately it doesn't work with my Redmi 9S.
USB C1 INPUT/OUTPUT: 5 / 9 / 12 / 15 / 20V 3A - PD 60W max. - Mainly for laptops
USB-A Output: 5V / 4.5A, 4.5V / 5A, 9V / 2A, 12V / 1.5A – QC 3.0, FCP, SCP, AFC
USB C2 Output: 5V / 3A, 9V / 3A, 12V / 2.25A, (PPS: 3.3V - 11V / 3A) DP 27W Max. - Mainly for smartphones
DC In: 12 - 24V 2A Max
DC Out: 12V / 4A, 16.5V / 4A, 20V / 4A, 24V / 3.5A
Important: Using DC and USB-C1 at the same time is not possible!
Info: Does not support low power devices including AirPods and smartwatches.
What is special here now is the 4 amps at 12V. I can use it e.g. to operate my LED video lamp. The huge 50,000mAh laptop power bank I looked at a few months ago couldn't do that, as it only delivered 2 amps at 12V — not enough for the lamp, which needs at least 3 amps. So always look at the power supply of your device. If it says "Output 12V, 3 amps", then the power bank should deliver 12V and at least 3 amps.
CPAP
It’s compatible with ResMed AirSense 10 (S10), ResMed S9, ResMed AirMini, Philips DreamStation System One 60.
It’s more accurate to say that it’s for CPAP emergency power in the airplane.
Because its capacity is under 88Wh, which is under 100Wh.
Power banks are allowed on planes, but they need to be under a specific capacity (100Wh) and they can only be taken in the carry-on luggage.
